Method for replacing subway track plate, subway plate replacing vehicle and plate replacing unit

Abstract

The invention discloses a method for replacing a subway track plate, a subway plate replacing vehicle and a plate replacing unit. The method comprises the following steps: firstly, defining a volume space of the plate replacing vehicle in a subway tunnel vehicle gauge; secondly, defining an operation space for replacing the track plate in the volume space of the plate replacing vehicle, namely replacing the old track plate with a new track plate in the volume space of the plate replacing vehicle to complete replacement operation of the track plate. The method, the subway plate replacing vehicle and the plate replacing unit are applicable to replacement of track plates outside and inside a subway tunnel. The method comprises fewer steps and is higher in replacement speed. The subway plate replacing vehicle and the plate replacing unit are simple in structure, easy and convenient to operate, high in replacement speed and high in replacement efficiency, the replacement operation of the track plate can be completed on time, and requirements for maintenance of the subway track plate are met.

Description

technical field [0001] The invention relates to a board changing method for replacing subway track boards, a subway board changing car and a board changing unit, and belongs to the technical field of subway track board replacement. Background technique [0002] The structure of the subway track is different from that of the traditional railway track, such as figure 1 As shown, its structure from top to bottom is a rail 1, a track plate 2, a CA mortar layer 3 and a concrete base 4, wherein the rail 1 is pressed and fixed on the track plate 2 by a rail fastener 5. After the subway runs for a period of time, the track slab is easily damaged. In order to ensure the safety of the vehicle, the damaged track slab must be replaced. [0003] However, when replacing the track slab for subway track maintenance, there will be some problems as follows: [0004] 1. Due to the special operating environment of the subway, most of the subway tracks are laid in the tunnel. However, when re...

AI Technical Summary

Problems solved by technology

[0010] The replacement method and replacement equipment in the above patent documents can only replace the subway track slabs laid outside the tunnel, and the required operating space and replacement equipment space for the replacement of the track slabs are large enough, which are not suitable for the track slabs inside the tunnel. Replacement, when the track slab that needs to be replaced is in the tunnel, the operating space of the replacement method in the above-mentioned patent document and the volume space of the replacement equipment are all beyond the vehicle limit in the tunnel, and the track slab cannot be replaced
